Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a positioning and laying device and method for siphon drainage board rolls. Background Technology

[0002] Siphonic drainage rolls have been widely used in projects such as sponge city construction, roof siphonic drainage, and underground garage roof drainage. These drainage boards typically consist of a drainage board body and a geotextile layer covering its surface. The geotextile usually extends beyond the edge of the drainage board to form an overlap. When rolled up, the overlap is folded inwards to cover the drainage board surface, preventing damage or contamination during transportation. During installation, it is unfolded and overlapped at the joints of adjacent drainage boards.

[0003] Existing construction methods mostly rely on manual labor with hand tools for laying, positioning, gluing, and pressing, which has the following problems: low accuracy of manual positioning, difficulty in maintaining consistent laying direction and joint width of drainage boards, and easy occurrence of deviation, wrinkles, and loose overlaps, affecting drainage effect; overlapping sections require manual folding, gluing, and compaction, which is cumbersome, labor-intensive, and inefficient; and it is difficult to achieve continuous, uniform, and straight-line laying when laying large areas, resulting in unstable joint quality and potential leakage problems later. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a positioning and laying device and method for siphon drainage board rolls, realizing integrated automatic construction of unwinding, positioning, gluing, folding, overlapping and compaction, thereby improving laying accuracy and construction efficiency.

[0005] To achieve the above objectives, the present invention employs a positioning and laying device for siphon drainage board rolls. The siphon drainage board roll includes a drainage board body and a geotextile layer covering the surface of the drainage board body. One side of the geotextile layer extends beyond the edge of the drainage board body and forms an overlap section for overlapping at the seam of two adjacent siphon drainage board rolls. In the rolled-up state of the siphon drainage board roll, the overlap section folds towards the drainage board body and covers the surface of the drainage board body. The positioning and laying device includes: The movable vehicle body; A roll support mechanism is provided at the front end of the trolley body. The siphon drainage board roll is rotatably connected to the roll support mechanism and can rotate and unwind as the trolley body moves forward. A positioning mechanism, mounted on the trolley body, is used to obtain the relative position information between the siphon drainage board roll and the preset laying position; An overlap mechanism is disposed in the middle of the trolley body and located on the unwinding path of the siphon drainage board roll. The overlap mechanism includes an adhesive feeding component, a folding component, and a compaction component. The adhesive feeding component is used to apply adhesive to the bonding surface of the overlap section. The folding component is used to guide the overlap section to fold outward and unfold. The compaction component is used to press the unfolded overlap section onto the adjacent siphon drainage board roll.

[0006] A further improvement of the present invention for the positioning and laying device of siphon drainage board roll material is that the roll material support mechanism includes: Two side panels are respectively connected to the bottom sides of the front end of the trolley body; Two limiting plates are located on the opposite inner sides of the two side plates, one of the limiting plates is fixed to the corresponding side plate, and the other limiting plate is adjustablely connected to the corresponding side plate to adjust the distance between the two limiting plates; Two insert rods are respectively connected to the opposite inner sides of the two limiting plates, allowing the two ends of the core of the siphon drainage board roll to be movably inserted.

[0007] A further improvement of the present invention for the positioning and laying device of siphon drainage board rolls is that the positioning mechanism includes: A laser emitter, which is arbitrarily connected to the front end of the trolley body, is used to emit laser lines corresponding to the designed edge lines of the siphon drainage board roll. A camera, whose position is adjustable, is connected to the front end of the trolley body to collect the relative position information between the laser line and the designed laying edge line in real time, so as to determine whether the siphon drainage board roll deviates from the designed laying position.

[0008] A further improvement of the present invention for the positioning and laying device of siphon drainage board rolls is that the compaction component includes: A support plate, height-adjustable, is connected to the bottom of the trolley body; The first pressure roller is tumbled to the bottom of the support plate and extends at one end toward the overlapping section, for compacting the unfolded overlapping section.

[0009] A further improvement of the present invention for the positioning and laying device of siphon drainage board roll material is that the adhesive delivery assembly includes: A glue tank is connected to the top of the trolley body, and a delivery pump is connected to one side of the glue tank; A brush is adjustablely connected to the bottom of the support plate and located between the first pressure roller and the roll material support mechanism. A glue delivery hose is connected between the brush and the delivery pump.

[0010] A further improvement of the positioning and laying device for siphon drainage board rolls of the present invention is that the folding component includes a flipping guide plate, which is adjustablely connected to the bottom of the support plate and located between the brush and the first pressure roller. The flipping guide plate is arranged along the unwinding path and is in an inclined and twisted posture to guide the overlapping section to fold outward and upward from the folded state.

[0011] A further improvement of the positioning and laying device for siphon drainage board rolls in this invention is that a push rod is connected to the top of the rear end of the trolley body, which is held by the construction personnel to push the trolley body to move.

[0012] A method for positioning and laying siphon drainage board rolls, comprising the following steps: Step 1: Provide the above-mentioned positioning and laying device for siphon drainage board rolls; Step 2: Install the rolled siphon drainage board material onto the roll support mechanism, and move the trolley body to the preset laying position of the siphon drainage board roll material; Step 3: Drive the trolley body forward and automatically unwind the rolled siphon drainage board material; Step 4: During the unwinding process, the relative position information between the siphon drainage board roll and the preset laying position is obtained through the positioning mechanism, and the position of the trolley body is adjusted according to the relative position information so that the siphon drainage board roll is laid along the preset laying position. Step 5: During the unwinding process, first apply adhesive to the bonding surface of the overlapping section through the adhesive feeding component, then fold the adhesive-coated overlapping section outward from the folded state covering the main surface of the drainage board through the folding component, and finally press the unfolded overlapping section onto the adjacent siphon drainage board roll through the compaction component.

[0013] A further improvement of the positioning and laying method for siphon drainage board rolls of the present invention is that the positioning mechanism includes: a laser emitter, which is arbitrarily connected to the front end of the trolley body; and a camera, which is arbitrarily connected to the front end of the trolley body. Before performing step 2 above, the design laying edge line of the siphon drainage board roll is popped out at the preset laying position. When performing step 2 above, the edge of the rolled siphon drainage board roll is aligned with the design laying edge line. When performing step 4 above, the positions of the laser emitter and the camera are adjusted so that the laser line emitted by the laser emitter corresponds to the design laying edge line. The relative position information between the laser line and the design laying edge line is collected in real time by the camera, and the position of the trolley body is adjusted according to the relative position information so that the laser line is aligned with the design laying edge line.

[0014] Compared with the prior art, the advantages of the present invention are: 1. The movable trolley body drives the drainage board roll to passively unwind, achieving continuous, uniform, and straight laying, which greatly improves construction efficiency.

[0015] 2. Real-time positioning and monitoring are achieved by combining a laser emitter and a camera to ensure that the edge of the drainage board is precisely aligned with the designed laying line, thereby ensuring the laying accuracy of the drainage board roll.

[0016] 3. An integrated overlap mechanism that combines glue application, folding, and compaction automatically completes the glue application, unfolding, and pressing of the overlap section, eliminating the need for secondary manual operations and improving construction efficiency.

Detailed Implementation

[0025] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0026] The positioning and laying device and its positioning and laying method for siphon drainage board rolls of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figures 1-6 As shown, a positioning and laying device for siphon drainage board rolls is provided. The siphon drainage board roll 3 includes a drainage board body and a geotextile layer covering the surface of the drainage board body. One side of the geotextile layer extends beyond the edge of the drainage board body and forms an overlap section for overlapping at the joint of two adjacent siphon drainage board rolls 3. In the rolled-up state of the siphon drainage board roll 3, the overlap section folds towards the drainage board body and covers the surface of the drainage board body. The positioning and laying device includes: The movable vehicle body 1; The roll material support mechanism 2 is located at the front end of the trolley body 1. The siphon drainage board roll material 3 is rotatably connected to the roll material support mechanism 2 and can rotate and unwind as the trolley body 1 moves forward. The positioning mechanism 4 is set on the trolley body 1 and is used to obtain the relative position information between the siphon drainage board roll 3 and the preset laying position. An overlap mechanism is located in the middle of the trolley body 1 and on the unwinding path of the siphon drainage board roll 3. The overlap mechanism includes an adhesive feeding component 5, a folding component 6, and a compaction component 7. The adhesive feeding component 5 is used to apply adhesive to the bonding surface of the overlap section. The folding component 6 is used to guide the overlap section to fold outward and unfold. The compaction component 7 is used to press the unfolded overlap section onto the adjacent siphon drainage board roll 3.

[0028] The movable trolley body 1 drives the siphon drainage board roll 3 to be unwound synchronously as it moves, and the positioning mechanism 4 achieves precise alignment. The overlapping mechanism simultaneously completes the gluing, folding and compaction during the unwinding process, realizing the integrated automatic operation of laying, positioning and overlapping of the siphon drainage board roll 3, which greatly improves the laying efficiency and positioning accuracy, and ensures stable and reliable overlapping quality.

[0029] Preferably, the coil support mechanism 2 includes: Two side panels 201 are respectively connected to the bottom sides of the front end of the trolley body 1; Two limiting plates 202 are located on the opposite inner sides of the two side plates 201, one of the limiting plates 202 is fixed to the corresponding side plate 201, and the other limiting plate 202 is tunably connected to the corresponding side plate 201 to adjust the distance between the two limiting plates 202. Two insert rods 203 are respectively connected to the opposite inner sides of the two limiting plates 202, and are respectively used for the two ends of the core of the siphon drainage board roll 3 to be inserted.

[0030] With the adjustable spacing of the limiting plate 202 and the matching insertion rod 203, siphon drainage board rolls 3 of different widths can be quickly clamped, and the clamping is stable and reliable, effectively improving the versatility of the device and the efficiency of material changing.

[0031] Specifically, a sliding rod 204 is connected to one side of the movable limiting plate 202. A sliding hole is provided on the side plate 201 for the sliding rod 204 to slide through. A limiting groove 205 is provided at the top of the sliding rod 204. An electric push rod 206 is vertically connected to the side plate 201. An anti-slip block 207 is connected to the bottom end of the electric push rod 206 for inserting and pressing against the limiting groove 205 to limit the sliding rod 204.

[0032] The sliding rod 204 cooperates with the sliding hole to achieve smooth sliding adjustment of the limiting plate 202. The electric push rod 206 drives the anti-sliding block 207 to insert into the limiting groove 205, which can quickly and firmly lock the adjusted position, ensuring stable and reliable locking, avoiding loosening and displacement during the laying process, and improving the stability and adjustment efficiency of the roll support.

[0033] Preferably, the positioning mechanism 4 includes: A laser emitter 401 is arbitrarily connected to the front end of the trolley body 1 and is used to emit laser lines corresponding to the designed edge lines of the siphon drainage board roll 3. Camera 402 is connected to the front end of the trolley body 1 in an adjustable position to collect the relative position information between the laser line and the designed laying edge line in real time, so as to determine whether the siphon drainage board roll 3 deviates from the designed laying position.

[0034] By combining the laser emitter 401 with the camera 402 to form a visual positioning monitoring system, the deviation between the drainage board laying position and the design edge line can be reflected in real time with high accuracy. The positioning is intuitive and accurate, effectively avoiding laying deviation and greatly improving the straightness of the laying and the accuracy of the seam alignment.

[0035] Specifically, the trolley body 1 includes a base plate 101, a second pressure roller 102, and a pair of wheel sets. The second pressure roller 102 is rotatably connected to the bottom rear end of the base plate 101 for compacting the laid siphon drainage board roll 3. The pair of wheel sets is adjustablely connected to the bottom front end of the base plate 101. Each wheel set includes: The connecting plate 103 is vertically fixed to the bottom front end of the base plate 101; A support column 104 is located on one side of the connecting plate 103. A roller 105 is connected to the bottom of the support column 104. The laser emitter 401 and the camera 402 are both connected to the support column 104. The lead screw 106 is arranged along the axial direction of the second pressure roller 102 and connected between the support column 104 and the connecting plate 103. The lead screw 106 is rotatably connected to the connecting plate 103. The support column 104 is provided with a threaded hole 107 for the lead screw 106 to pass through. The first guide rod 108 is arranged along the axial direction of the second pressure roller 102 and one end is connected to the support column 104. The connecting plate 103 has a first guide hole 109 for the first guide rod 108 to pass through.

[0036] The wheel spacing is adjusted by the screw 106 and the first guide rod 108, and the laser emitter 401 and camera 402 are integrated and installed on the support column 104. The positioning reference and walking distance can be flexibly adjusted according to the actual width of the siphon drainage board roll 3, and the adjustment is precise and stable. At the same time, the laser and camera positioning are synchronized with the wheel set, ensuring that walking and positioning are always coaxial and synchronized, further improving the laying accuracy and device adaptability.

[0037] Preferably, the compaction component 7 includes: A support plate 701 is height-adjustably connected to the bottom of the trolley body 1; The first pressure roller 703 is roll-connected to the bottom of the support plate 701 and extends one end toward the overlapping section to compact the unfolded overlapping section.

[0038] The height-adjustable support plate 701, together with the special first pressure roller 703 for the overlapping section, can be adapted to siphon drainage board rolls 3 of different thicknesses and base surfaces of different heights, accurately compacting the overlapping parts, making the overlapping section more firmly bonded, improving the overlapping sealing effect and construction versatility.

[0039] Specifically, a hydraulic cylinder 702 is connected between the support plate 701 and the trolley body 1. A second guide rod 704 is also vertically connected to the top of the support plate 701. A second guide hole is provided on the trolley body 1 for the second guide rod 704 to pass through.

[0040] Driven by hydraulic cylinder 702 and guided by second guide rod 704, the height of support plate 701 and first pressure roller 703 can be stably adjusted. The adjustment process is smooth and reliable, with strong support rigidity, ensuring uniform compaction pressure in the overlapping section, effectively improving the overlapping quality and the stability of the device operation.

[0041] Preferably, the glue dispensing assembly 5 includes: A glue tank 501 is connected to the top of the trolley body 1, and a delivery pump is connected to one side of the glue tank 501. The brush 502 is adjustablely connected to the bottom of the support plate 701 and is located between the first pressure roller 703 and the roll material support mechanism 2. The brush 502 is connected to the conveying pump by a glue delivery hose 503.

[0042] By using a glue tank 501, a delivery pump, and an adjustable brush 502, glue can be continuously and evenly applied to the overlapping sections during the laying process. The glue application position is precise and controllable, effectively improving the reliability of bonding and the continuity of construction.

[0043] Preferably, the folding assembly 6 includes a flipping guide plate, which is adjustablely connected to the bottom of the support plate 701 and located between the brush 502 and the first pressure roller 703. The flipping guide plate is arranged along the unwinding path and is in an inclined and twisted posture to guide the overlapping section to fold outward and upward from the folded state.

[0044] The flipping guide plate adopts an inclined torsion structure and is adjustable in position, which can smoothly guide the overlapping section, allowing the overlapping section in the winding state to flip naturally and avoid tearing or wrinkling.

[0045] As shown in Figure 6, the flipping guide plate has an overall twisting trend, but the starting section is flat and is used to insert at the bottom of the overlapping section. The width of the starting section is adapted to the width of the overlapping section so that when the trolley body 1 is driven forward, the overlapping section that is folded inward and pressed during winding first fits against the starting plane to support and limit the position, and then gradually unfolds outward and upward along the twisting arc of the plate.

[0046] Specifically, a movable rod 9 is arbitrarily connected to the support plate 701. A guide groove 10 extending axially along the first pressure roller 703 is provided on the support plate 701. The movable rod 9 includes a vertical rod and a C-shaped rod. The web of the C-shaped rod passes through the guide groove 10 and can slide along the extension direction of the guide groove 10. The vertical rod is located on the side of the support plate 701 relatively close to the coil support mechanism 2 and is connected to the two flanges of the C-shaped rod. The brush 502 and the flipping guide plate are both connected to the bottom of the vertical rod. A limiting member for limiting the movable rod 9 is connected to the C-shaped rod.

[0047] By cooperating with the movable rod 9 and the guide groove 10, the brush 502 and the flipping guide plate can be precisely moved to the corresponding position of the overlapping section, so that the gluing and folding operations are completely aligned with the overlapping section, ensuring uniform gluing and proper folding, and greatly improving the overlapping accuracy and construction quality.

[0048] Specifically, the limiting member includes a first pin 11, a first insertion hole for inserting the first pin 11 is provided on the top flange of the C-shaped rod, and a plurality of second insertion holes for selective insertion of the first pin 11 are provided on the support plate 701 along the extension direction of the guide groove 10.

[0049] The limiting structure, which uses the first pin 11 in conjunction with multiple sets of holes, can quickly lock the brush 502 and the flipping guide plate in the corresponding position of the overlapping section. The positioning is accurate and the locking is firm. It does not shift during operation, and the adjustment is simple and efficient, ensuring that the gluing and folding are always accurately aligned with the overlapping part.

[0050] Specifically, the height of the movable rod 9 is adjustable, and a second pin is connected between the movable rod 9 and the support plate 701. A plurality of third insertion holes are spaced apart along the length direction on the vertical rod for selective insertion of the second pin, and a plurality of fourth insertion holes are spaced apart along the extension direction of the guide groove 10 on the end face of the support plate 701 for selective insertion of the second pin.

[0051] The second pin can be selected with a third insertion hole of different heights and a fourth insertion hole of different positions to achieve dual positioning and locking of the moving rod 9 along the extension direction of the guide groove 10 and vertically. It can finely adjust the height of the brush 502 and the flip guide plate from the ground and the horizontal position as needed, accurately match the overlapping section of the drainage board of different specifications, lock firmly, and prevent displacement during operation, ensuring the accuracy and stability of the gluing and folding process.

[0052] Preferably, a push rod is connected to the top of the rear end of the trolley body 1, which is held by construction workers to push the trolley body 1 to move.

[0053] By setting the push rod at the rear end of the trolley body 1, construction personnel can hold it steadily to apply force, making it easier to move the device and more flexible to operate, thus improving the overall construction convenience and stability.

[0054] Specifically, the push rod is connected to a display 8, which, together with the camera 402, is used to display the relative position information in real time and to trigger an alarm when the relative position information is detected to be outside the allowable error range.

[0055] By integrating the display 8 into the push rod and linking it with the camera 402, the laying position deviation information can be displayed in real time. If the deviation exceeds the error range, an alarm will be automatically triggered, which will facilitate the operator to correct the deviation in time and further improve the positioning and laying accuracy and construction reliability.

[0056] A method for positioning and laying siphon drainage board rolls, comprising the following steps: Step 1: Provide the above-mentioned positioning and laying device for siphon drainage board rolls; Step 2: Install the rolled siphon drainage board roll 3 onto the roll support mechanism 2, and move the trolley body 1 to the preset laying position of the siphon drainage board roll 3; Step 3: Drive the trolley body 1 forward and automatically unwind the rolled siphon drainage board material 3; Step 4: During the unwinding process, the positioning mechanism 4 obtains the relative position information between the siphon drainage board roll 3 and the preset laying position, and adjusts the position of the trolley body 1 according to the relative position information so that the siphon drainage board roll 3 is laid along the preset laying position. Step 5: During the unwinding process, the adhesive is first applied to the bonding surface of the overlapping section through the adhesive feeding component 5, and then the overlapping section after applying the adhesive is folded outward from the folded state covering the main surface of the drainage board through the folding component 6. Finally, the unfolded overlapping section is pressed onto the adjacent siphon drainage board roll 3 through the compaction component 7.

[0057] Preferably, the positioning mechanism 4 includes: a laser emitter 401, which is position-adjustably connected to the front end of the vehicle body 1; and a camera 402, which is position-adjustably connected to the front end of the vehicle body 1. Before performing step 2 above, the design laying edge line of the siphon drainage board roll 3 is popped out at the preset laying position. When performing step 2 above, the edge of the rolled siphon drainage board roll 3 is aligned with the design laying edge line. When performing step 4 above, the positions of the laser emitter 401 and the camera 402 are adjusted so that the laser line emitted by the laser emitter 401 corresponds to the design laying edge line. The relative position information between the laser line and the design laying edge line is collected in real time by the camera 402, and the position of the trolley body 1 is adjusted according to the relative position information so that the laser line is aligned with the design laying edge line.

Step 5: During the unwinding process, the adhesive is first applied to the bonding surface of the overlapping section through the adhesive feeding component. Then, the overlapping section after applying the adhesive is folded outward from the folded state covering the main surface of the drainage board through the folding component. Finally, the unfolded overlapping section is pressed onto the adjacent siphon drainage board roll through the compaction component.

9. The positioning and laying method for siphon drainage board rolls as described in claim 8, characterized in that, The positioning mechanism includes: a laser emitter, which is tunably connected to the front end of the vehicle body; and a camera, which is tunably connected to the front end of the vehicle body. Before performing step 2 above, the design laying edge line of the siphon drainage board roll is popped out at the preset laying position. When performing step 2 above, the edge of the rolled siphon drainage board roll is aligned with the design laying edge line. When performing step 4 above, the positions of the laser emitter and the camera are adjusted so that the laser line emitted by the laser emitter corresponds to the design laying edge line. The relative position information between the laser line and the design laying edge line is collected in real time by the camera, and the position of the trolley body is adjusted according to the relative position information so that the laser line is aligned with the design laying edge line.
